Diagnose and Resolve Your Connectivity Performance Issues

Accurate speed testing and troubleshooting help identify whether performance dips are caused by local hardware or external network factors.

Common questions about Performance Issues.

I think my connection is slow. What can I do?

If your connection feels slow, start by restarting your router and checking whether the issue happens on all devices or just one; then make sure you’re connected to the best signal (use 5GHz WiFi if available for faster speeds), move closer to the router or reduce obstacles like thick walls, and disconnect unused devices that may be consuming bandwidth (like downloads, streaming, or updates); you can also try using a wired Ethernet connection for the fastest and most stable performance, and if the speed is still consistently low, it’s worth checking your package speed and contacting Kerry Broadband support to test the line and confirm there are no service or network issues in your area.

What details do you require to assist my query?

To help you quickly and accurately, I may need a few basic details depending on the issue, such as your account name or customer ID (to find your connection), your installation address (to check service availability or line status), a description of the problem (e.g. slow internet, no connection, WiFi issues), the type of device or router you’re using, and when the issue started; for some technical problems, it also helps to know if all devices are affected or just one, so the support team can properly diagnose and resolve your query.

I have an IPTV streaming box that buffers

If your IPTV streaming box is buffering, it’s usually caused by a weak internet connection, network congestion, or limitations in WiFi stability; first check if other devices are also slow, then try restarting your router and IPTV box, and if possible connect the box directly to the router using an Ethernet cable instead of WiFi for a more stable stream; if you must use WiFi, try switching to the 5GHz band and place the box closer to the router or reduce obstacles between them, and also make sure no other devices are heavily using the internet (like downloads or HD streaming), as IPTV needs a steady bandwidth to work smoothly without interruptions.

More about speed tests

A speed test measures how fast your internet connection is working at a given moment by checking three main things: download speed (how quickly data comes to you, important for streaming and browsing), upload speed (how quickly you send data, important for video calls and uploads), and ping/latency (how fast your connection responds, important for gaming and live streaming). To run a proper speed test, connect your device directly to WiFi (or better, via Ethernet cable), close other apps or downloads, and use a trusted test like Ookla Speedtest; if your results are much lower than your plan speed, it could indicate WiFi issues, router placement problems, or a line/network issue that may need troubleshooting or support from Kerry Broadband.

I am paying for a specific speed. Why do I not get that speed

It’s very common not to see the exact “up to” speed you pay for all the time, because broadband performance depends on a few real-world factors: your connection type (fibre, wireless, or mixed), WiFi limitations (walls, distance, interference, and older routers often reduce speed), how many devices are using the internet at the same time, and whether you’re testing over WiFi instead of a wired Ethernet connection. The advertised speed is usually the maximum possible line speed under ideal conditions, while actual speeds can vary during busy hours or due to network load in your area. For the most accurate result, try a wired speed test directly from the router, and if speeds are still significantly below what you’re paying for, it may indicate a line or network issue that Kerry Broadband support can check and help resolve.

What is contention?

Contention is when multiple internet users in your area share the same network capacity from your provider, so during busy times (like evenings), more people using streaming, gaming, or downloads can reduce the available speed for everyone, which may result in slower internet than usual even if your plan supports higher speeds; it’s a normal part of how broadband networks work, and it’s usually more noticeable on shared networks compared to dedicated fibre lines, especially during peak usage hours.
